Excitation function of the Fe(p,)51Mn reaction was measured from 9.5 to 18 MeV by activating a foil stack of Fe electrodeposited on copper substrates. Residual radionuclides were quantified by HPGe gamma ray spectrometry. Both Mn ( = 46.2 min, , ; = 749.1 keV, = 0.265%) and its radioactive daughter, Cr ( = 27.704d, = 320.1 keV, = 9.91%), were used to indirectly quantify formation of Mn. Results agree within uncertainty to the only other measurement in literature and predictions of default TALYS theoretical code. Final relative uncertainties are within ±12%.
通过活化沉积在铜衬底上的铁箔堆，测量了9.5至18 MeV能量范围内Fe(p,γ)51Mn反应的激发函数。通过HPGeγ射线能谱法对残留放射性核素进行定量分析。利用Mn（半衰期 = 46.2分钟，发射γ射线，能量为749.1 keV，丰度为0.265%）及其放射性子体Cr（半衰期 = 27.704天，发射γ射线，能量为320.1 keV，丰度为9.91%）间接定量Mn的生成量。结果在不确定度范围内与文献中唯一的其他测量结果以及默认TALYS理论代码的预测结果一致。最终相对不确定度在±12%以内。
